CLUTCH.

SPECIFICATION forming part of Letters Patent No. 463,895, dated November 24, 1891.

Application filed August 18, 1891. Serial No. 403,017. (No model.)

To all whom it may concern.-

Beit known that I,WILLIAM GOLDSWORTHY, of Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Friction-Clutches; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure 1 is a face View of a friction-clutch, partly broken away. Fig. 2 is a vertical central transverse section through Fig. 1.

This invention is a friction clutch, and is an improvement upon the clutch for which 1 filed application for Letters Patent of the United States on the 3d day of June, 1891, Serial No. 394,937, and the objects of this invention are to simplify the construction of and strength en the said clutch; and it consists in the improved novel construction and combination of parts hereinafter clearly specified.

Referring to the drawings by letter, S and S are the driving and driven line-shafts.

A is a flanged disk or pulley on shaft S, and D an oppositely-facing smaller disk keyed on shaft S ,with its flanged periphery lying within the flange of disk A. The flange of disk D has equidistant recesses d, in which fit the shanks c of friction shoes 0, interposed between the flange of disks A D, as shown.

J is an annulus loosely mounted on the end of shaft S between disks A D, and G indicates links pivotally connected to the annulus and to the severalshoes, passing through slots d in the bottom of recesses d, as shown. The outer ends of links G are slotted to allow shoes 0 to move freely. The annulus J can be shifted by means of rods K, connected to the grooved collar, (not shown,) as set forth in my aforesaid application, and all the foregoing parts are substantially like the same parts in said application.

E designates gibs interposed between the tops of links G and the top walls of shoes C, and having their screwthreaded ends proj ecting through openings 6' in the shoes and securely retained by adjusting and set nuts f thereon, as shown. Coiled springs F are slippedon the gibs between the outer wall of the shoe and a pin (2 on the gib, as shown,

which normally tend to force the gibs inward. The wedge ends of the gibs lie between the ends of links G and shoes, so that by adjusting these gibs the shoes are adjusted radially toward or from the axes of the disks.

0 O are pins connected to the lower edge of shoe 0 and projecting through openings (1 d in the bottom of recesses d. The lower ends of said rods are screw-threaded and on them are nuts 0 0. Springs I I are placed on said rods between nuts 0 and the bottom of recesses d and tend to draw shoes 0 inward and out of contact with the flange of disk A. By shifting annulus. J in one direction the links G, which are normally inclined to the peripheries of the disks,are throwninto nearly vertical position in relation thereto, thereby I forcing shoes 0 outward and binding them firmly against the flange of disk A, thus looking the disks together and causing them to transmit motion from one shaft to the other or from one loose to one keyed disk.

In my aforesaid application the wedge-gibs were placed under the links. In this case they are placed over the links, avoiding the necessity for tubes around the gib-shanks, and also permitting the hubs of the disks to be enlarged and strengthened and the gibs to be more conveniently placed for adjustment. Again, instead of placing springs around the links they are placed directly beneath and connected to the shoes and can be finely adj usted,,and rods 0 guide the shoes and cause them to move straight out. Hence there is no need for the annular rim on the outer wheel to retain the shoes in position.

Having thus described my invention, I claim 1. The combination of the flanged disks, the radially-movable shoes, the movable annulus between the disks, the links pivotally connecting the shoes and annulus, and the gibs for adjusting said shoes, adj ustably mounted in said shoes between the same and ends of links, substantially as specified.

2. In a friction-clutch, the combination of an outer flanged disk, an inner flanged disk, a series of radially-movable shoes interposed between the flanges of the disks, the radiallymovable links for throwing said shoes outward, and means for shifting said links, with the rods fixed to and depending from said shoes beside the links and playing through openings in the flange of the inner disk, and the springs and nuts for adjusting said rods and shoes, substantially as and for the purpose specified.

3. The combination of the inner and outer disks, the radially-movable shoes interposed between the flanges of said disks, the annulus and links connecting the same to the shoes for throwing the latter outward, and springs for throwing the shoes inward, with the ad j ustable gibs interposed between the ends of the links and shoes, substantially as set forth.

it. The combination of the flanged disk, the inner flanged disk havingrecessesin its flange, the radially-movable shoes seated in said recesses, and the links pivotally connecting the shoes to a movable annulus, and the springcontrolled gibs carried by the shoes and in- 20 terposed between the shoes and tops of links,

and the nuts for adjusting said gibs, substantially as specified.

5. The combination of the flanged disks, the radially-movable shoes, and the spring-controlled rods connected to the shoes and playing through the flange of the inner disk, with the movable annulus between the disks, the links pivotally connecting the shoes and annulus, and the gibs for adjusting said shoes mounted in the shoes between the same and ends of links, all constructed and arranged to operate substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
